The United States Postal Service (USPS) has a long history of connecting people, governments and businesses and touches every American household. This organization processed and delivered 154 billion pieces of mail in 2016 or 47% of the world’s mail volume. It employs over 630,000 people and operates 31,000 retail offices as well as 230,000 vehicles. With the large and complex operations, the organization continuously strives for operational excellence. It heavily invests in Industrial Engineering (IE) and leverages Continuous Improvement and Lean Six Sigma Philosophy. The USPS employs over 400 Industrial Engineers and is one of the largest IE employers in the US. This seminar will introduce the audience to the IE and Lean Six Sigma journey at the USPS. We will show you how IE techniques and Lean Six Sigma Principles are being utilized and how they play an important role in improving the processes in the 200 year plus old organization. We will explore every facet of mail processing and show you how a mail piece travels through these processes. We will show you how the USPS does not just survive but also thrives in the digital era by leveraging not just technology but also Lean Six Sigma Principles. We will show some of the process improvement projects using Lean Six Sigma tools such as Statistical Process Control Chart, Gemba Walk, Kanban, Ishikawa Diagram, Spaghetti Diagram, Line Balancing and Setup Reduction.
